Why do rides lasting longer than 30 minutes cost more?

Bike share is designed for short rides and one-way trips from station to station, kind of like a human-powered subway. Rides are limited in length to make sure that bikes are available for all users to “share” throughout the day. That’s why only the first 30 minutes of each ride are included in the pass price, and why extra fees apply for longer trips – to encourage riders to use bike share for short trips and to return their bikes within a relatively short period of time. If you arrive at a station and find there are no available docks, you may use the kiosk to request an additional 15 minutes of free time be added to your trip and find a nearby station with available docking spaces.
